This is great. A compact little game, with enough original content (GOOB) that is also well put together to make the whole experience feel complete compared to the rough drafts of other games.
I do second that other guy, the "odd goober," or "odd one out" as I understand it, isn't exactly clear the first or few times you see it. Once you know what that means it works. Maybe for the first couple rounds of "odd goober," make the odd ones more obviously odd to help players catch on to what that means. One or two goobers walking backwards is more noticeable than three or four waving with their left hands.
